Campaigns

Sequences that branch on real signals, throttled per inbox, native-feeling variation, scheduled in the lead's timezone. Build the campaign once, let the platform run it correctly.

Multi-step sequences with conditional branching
Up to 20 steps. Branch on opened / clicked / replied / silent. Delays in business days, calendar days, or hours.
if reply.classification == "interested": pause_sequence(); route_to("fast-follow")
A/B testing that doesn't make you do statistics
Up to 4 variants per step (subject, body, CTA). We track impressions and replies, run significance math in the background, and promote the winner automatically once you cross the threshold.
two-tail test · p < 0.05 · auto-promote on threshold crossing
Spintax for native-feeling variation
{Hi|Hey|Hello} {firstName}, rotates across recipients so no two see identical copy. Important for deliverability and personalization both.
3+ depth nesting · per-sequence seed for reproducibility
Per-inbox throttling and weighted rotation
Distribute volume based on health score, days in warmup, and historical reply rate. New inboxes get less load. Burnt-out inboxes auto-pause.
weights re-balanced every 4h based on health signals
Send-time windows in the lead's timezone
Lead is in Sydney? imail respects that. 9am–5pm local, weekdays only — configured per campaign.
IANA timezone database · DST-aware · holiday calendars (US/EU/UK)

Inbox management

Connect what you already have. Watch its health. Reconnect when it drops. The boring operational stuff, automated.

Unlimited inboxes
Any SMTP/IMAP provider — Google, Microsoft 365, Zoho, FastMail, custom servers. No surcharge per inbox. We don't gate on connection count.
Health monitoring with auto-reconnect
Every connected inbox has a live health score. When a connection drops, imail reconnects with exponential backoff and resumes any queued sends from where they stopped. No emails get lost.
1s → 2s → 4s → 8s → 16s → 30s cap · on-disk queue · resumable
Bulk reconnect, bulk pause, bulk anything
50 inboxes failed because Google rotated OAuth scopes? One click reconnects them all.
Domain aging tracker
Track how long each sending domain has been active. New domains get auto-throttled until they've aged past 14 days.
day 1–14: throttled · day 15+: full schedule · re-aging if reputation drops

Deliverability

Real-time domain reputation, blocklist monitoring, DMARC alignment, SPF/DKIM/DMARC wizard, placement testing across 12+ ESPs, spam content checker, ESP-matched bounce handling.

Replies & Unibox

Every reply from every mailbox in one view, classified, threaded, and routed by intent. Stop reading auto-replies.

Unified inbox
Every reply from every connected mailbox in one view. Threaded conversations. Read/unread tracking. Assign to a teammate. Star, archive, search.
AI reply classification
iBrain reads every reply and tags it. You stop scrolling past 50 auto-replies to find the one human response.
labels: interested · not-interested · needs-info · out-of-office · auto-reply · other
Suggest-a-reply
Click "Suggest reply" on any thread. iBrain reads the full conversation and drafts a response in your tone. Edit, send.
Auto-route on intent
Set a rule: "If reply is classified Interested, pause sequence and add to follow-up campaign." Hot leads stop getting "did you see this?" emails.

iBrain (AI)

Claude-powered, not GPT. Email generation, subject line variations, copy improvement, deal scoring, next-best-action suggestions, knowledge-base-aware product Q&A.
